Internet of Things and its applications

  1. 1. Internet of Things and its applications Pasquale Puzio Sistemi e Reti Wireless a.a. 2010/2011 Università di Bologna
  2. 2. What's Internet of Things
  3. 3. CISCO'S PREVISION In 2008 the number of things connected to the Internet was greater than the people living on Earth. Within 2020 the number of things connected to the Internet will be about 50 billion .
  4. 4. Definition CERP-IOT: Internet of Things (IoT) is an integrated part of Future Internet and could be defined as a dynamic global network infrastructure with self configuring capabilities based on standard and interoperable communication protocols where physical and virtual ‘things’ have identities, physical attributes, and virtual personalities and use intelligent interfaces, and are seamlessly integrated into the information network. In the IoT, ‘things’ are expected to become active participants in business, information and social processes where they are enabled to interact and communicate among themselves and with the environment by exchanging data and information ‘sensed’ about the environment, while reacting autonomously to the ‘real/physical world’ events and influencing it by running processes that trigger actions and create services with or without direct human intervention. Interfaces in the form of services facilitate interactions with these ‘smart things’ over the Internet, query and change their state and any information associated with them, taking into account security and privacy issues.
